Title: Improvements in extrusion presses with means for measuring the exit speed of the extruded product
IPC: B21C31/00
Filed: 1960-11-17
Abstract: 902,053. Extruding. SCHLOEMANN A.G. Nov. 17, 1960 [Dec. 21, 1959], No. 39480/60. Class 83 (4). A metal rod or tube extrusion press has means employing a linear indicator or signal emitter for measuring the exit speed of the extruded product as a numerical value per unit of time or for regulating the speed. A transverse arm 6a mounted on the main press ram 5 actuated by an hydraulic piston 4, carries a channel bar with a forked abutment 6 working between adjustable setting rings 16, 17 on a slidable tube 15. This is connected through a spring coupling 39, Fig. 7 (not shown), and a clamp with a diffraction-grating bar 7 which corporates with a lamp 9 diffractiongrating plate 13 and photo-electric cell 10 to produce a pulsating voltage 60 which is converted by an impulse former 63 into rectangular pulses 64. These pass through a gate 65 to a counter 68 and then through a storage device M and amplifier V to a luminous dial indicator 74 which records the number of pulses per unit time and thus the extrusion speed. To compensate for changes in the length of the ram which occur due to the extrusion pressure, a piston 45 is subjected to the pressure in the press cylinder 1 and moves a second diffractiongrating bar 47 working between a light source 48 and photo-electric cell 51 whereby further rectangular pulses formed at 70 are passed to the counter 68 where they are added or subtracted to the other pulses. An oscillator 77 and frequency reducer system 76 are used to trigger the gate 65. The actual value of the extrusion speed may be compared with a desired value produced by the system 76, 77, in a counter 78 and to give a regulating value which is used to correct the press speed automatically. Two separate pulse counters and dial indicators may be coupled in parallel, Fig. 2 (not shown), for recording alternate time cycles.

Title: Two wire full duplex data transmission system
IPC: H04Q3/58
Filed: 1975-10-03
Abstract: 1522682 Duplex data transmission NORTHERN TELECOM Ltd 3 Oct 1975 [16 Oct 1974] 40614/75 Headings H4P and H4M In a full duplex transmission system, more particularly for the control channel of a 4-wire telephone system, data from the local station has two transitions for bits of one level and four transitions for the other level. At the remote station two sync pulse trains are produced, one for each transition rate and these are used to decode the signal. Signals are returned to the local station at the lower transition rate, the delay in the transmission being less than half the period of the lower rate. A data "1" at 5 is gated by half rate clock pulses through NAND gate 20 and flip-flop 21 in synchronism with the full rate clock. When the data is "0" full rate pulses are gated through the Exclusive OR gate 23. The resulting signals (Fig. 2F not shown) pass through a hybrid and filter circuit 24 to line as diphase signals. On reception incoming signals are squared and provided with DC bias by 32, energizing, via steering circuit 33, a non-retriggerable monostable circuit 34 having an upset time of between half and one period of clock rate. Regenerated signal from 34 is applied, via inverting amplifier 35, to CL input of flip-flop 36 together with an input from 32 producing a partly decoded signal; OR gate 37 and flip-flop 38 provide half rate signals in phase with lower rate portion of di-phase signals. Flip-flop 38 also receives an output from 34 to provide half rate clock signals (Fig. 2J) which are applied to a flip-flop 39 to complete decoding process, output being passed to supervisory circuit 13 of unspecified purpose. Flip-flop 38 is reset by OR'ed inputs from flip-flop 36 in the event that output is out of phase with slower rate portion of di-phase signal. Supervisory circuit 13 also generates binary data applied through flip-flop 40 OR 41 both receiving half rate clock pulses from 38, and hybrid circuits 30, 24 to shape V 52 which squares, also restores DC bias on reception before decoding at 53 by half rate clock pulses.

Abstract: 1,166,814. Reservoir pens. GNTHER WAGNER PELIKAN-WERKE. 16 Sept., 1966 [16 Sept., 1965], No. 41516/66. Heading B6P. In reservoir pens including a cleaning wire 24 attached to a piston 23, the piston moves in a chamber 32 substantially free of ink, and the ink flows to the point outside the chamber 32. The chamber 32 is formed by a tube 7 closed at its inner end by a block 22 attached to one part 4 of a two-part member 4, 5. Ink can flow from a reservoir 6 into a capillary space 20 between the tube 7 and parts 4, 5 by way of passages in the periphery of the block 22. At its forward end the tube 7 has an opening 25 filled by the wire 24 to prevent ink entering the chamber 32. The opening 25 is formed in a conical part seating on a similarly-shaped part of member 5 with capillary passages in between to permit ink to pass from the space 20 to a relatively-large opening 26 in the member 5 and thence to the tubular nib 27. The nib 27 is carried by a part 28 detachably connected to member 5. In the rearward position of the piston 23, the end of the wire 24 does not project beyond the end of opening 26 thus preventing damage to the wire if the parts 27, 28 are replaced. A shoulder 2 on the front section 1 of the barrel engages a shoulder 19 on the member 5 to hold the parts in place. The space 18 between the parts 1, 4, 5 is open to atmosphere through a passage 16 and interconnected annular grooves 14, 15 in the member 5. At its inner end member 4 has a flange 9 with an eccentric annular groove 10. The groove 10 is connected with the reservoir 6 by means of a groove 12 parallel to the axis and with the space 18 by a diametrically opposite groove 13. Air can thus pass into the reservoir from space 18 via passages 10, 12, 14. The space 18 also forms an overflow reservoir if an expansion in the reservoir causes ink to be forced out of the reservoir 6. A capillary groove 29, Fig. 2 (not shown), is provided at each side of the groove 12 to allow ink to pass if the groove 12 is blocked by an air bubble. Reference has been directed by the Comptroller to Specification 784,388.

Abstract: 1287825 Automatic brightness control C G R MEDICAL CORP 2 Sept 1970 [24 Sept 1969] 41927/70 Heading G3R [Also in Divisions G1 and H3] X-ray tube control circuit for exposure or brightness control in x-ray radiography, fluoroscopy or cine, includes means for selecting one of a plurality of x-ray detectors and connecting it to an operational amplifier which is provided with means whereby it may operate in an integration mode for exposure termination or in a signal amplifier mode for brightness control. Detectors may be photo-multipliers 10, 20, 30, one of which is selected by closing of switch 11, 21 or 31, which might be controlled by external logic circuitry, punched cards, tape &c. Resultant conduction of e.g. transistor 12 causes potentiometer 13, which is set to a position appropriate to the particular use and location of detector 10, to deliver current at an appropriate value to amplifier 41, 42 and inverter 40, which delivers the photo-multiplier 10 supply voltage at the required value. If this same voltage is also supplied to the other detectors 20, 30 these are shielded so as to have negligible output. Closing of switch 11 also results in conduction of transistor 17 via zener 15 and diode 16, thereby coupling the detector 10 output to the operational amplifier 50. This comprises differential arrangement 51, 52 feeding transistors 53, 54 in cascade. Feedback via capacitor 56 provides for the integration mode. The setting of 71 determines the voltage at which transistor 72 will conduct to terminate the exposure (70). Exposure is initiated via gating transistor arrangement 91, 92. For brightness control purposes, typically in fluoroscopy and cine, switch 61 is closed to provide the signal amplifier mode. This causes feedback via resistor 59 and capacitor 59 through transistor 62 to the amplifier input at 51. The output of the amplifier 50 is used at 80. Switching in of this shunt R.C. circuit provides facility for following steady state variations up to a few  cycles and then smoothing. Typical locations for the tubes are: adjacent a scintillator (in radiography); coupled to image-intensifier output phospher; at spotfilm device; under x-ray table.
